Many dealers would feel insulted and be mad if you tipped $5k. It's retarded, but that's how it is. When I dealt, there was a dealer during break that said he paid off some "big" jackpot.....like $10k, IIRC. He got tipped $500 and was mad -- wanted 20% because "that's the standard amount you should tip" or some dumb shit.
On $82k, I think I'd tip $500 if it goes directly to the dealer and $200 (max) if pooled. Of course, there are other unknown factors that might increase or decrease the amount. If the dealer's been rude or suddenly starts being annoying trynna hustle a tip, then $0......ehhhh, maybe $5 just to spite them.
